摘要

为减小现代有轨电车短时大功率的充电方式对配电网产生的容量冲击,在充电装置中加入超级电容串并联组成的储能系统。电车到站前,由配电网以低功率向充电装置内储能系统充电,整流器网侧接入LCL滤波器以减小交流侧的谐波,并采用输出电压-网侧电感电流双闭环的控制策略;列车到站后,充电装置内储能系统向有轨电车充电,根据超级电容的充电特性,采用先恒流后恒压的控制策略。最后仿真验证了充电系统的可行性。
        An energy storage system composed of super-capacitors in series-parallel connection was added to the charging device so as to reduce the capacity impact caused by the short-time high-power charging mode of modern trams. Before the tram arrived at a station,the distribution network charged the energy storage system in the charging device with low power,and an LCL filter was connected to the rectifier network side to reduce the harmonics at the AC side. Furthermore,a control strategy of double closed loop( for inductance and current) was adopted at the output voltage network side. After the arrival of the train,the energy storage system in charging device charged the tram. According to the charging characteristics of the super-capacitors,a control strategy of constant current followed by constant voltage was adopted. Finally,simulation results verified the feasibility of the proposed charging system.
